Tritium Beta Decay

³H → ³He + e⁻ + ν̄_e

Genel Bakış

Tritium (hydrogen-3) undergoes beta decay to helium-3 with a half-life of 12.3 years, emitting a very low energy electron (max 18.6 keV). The low beta energy means tritium radiation cannot penetrate skin and is only hazardous if ingested or inhaled. Tritium is produced in nuclear reactors and by cosmic rays.

Günlük Örnek

Self-luminous exit signs and watch dials use tritium gas sealed in phosphor-coated glass tubes that glow without batteries for over 10 years.

Endüstriyel Önemi

Tritium is used in self-luminous devices, as a tracer in hydrology, in nuclear weapons, and as fuel for D-T fusion reactors.
